The swine flu outbreak from 2009 is not over, rather on the contrary. The (H1N1) virus is now common in flu season.
– “Influenza A (H1N1) from 2009 has become a seasonal flu that circulates regularly. Such is the case after a pandemic, then the virus continues to circulate,” says adviser Birgitte Klüwer from the department of influenza at the Norwegian Institute of Public Health to forsking.no.
When the pandemic broke out, infection was associated with serious illness and worst cases resulted in death for some in some groups among us. Across the country people went to get vaccinated so to limit the contagion.
The reason why no one speaks particularly much about the serious threat of swine flu infection now, is because the virus is still around. Several have gained resilience because they have been exposed to the virus earlier.
“The body learns to defend itself against individual viruses,” says Klüwer.
This year’s vaccine for risk groups contains components of two types of A-influenza and one B-influenza, and A (H1N1) is one of these.
